Attic Insulation in Casar
About 35 percent of Casar's homes predate 1970; if your joists show above the insulation, ENERGY STAR says to add more insulation.
The Local Climate
Casar's center sits about 1,140 feet above sea level, 10 miles from NOAA's Vale Ag 2 SW station, the best match for Casar. The station's 1991 to 2020 normals average about 3,890 heating and 1,260 cooling degree days a year, so at Casar's station, heating needs outweigh cooling.
Casar sits about 150 feet above the station, so expect slightly colder winters.

Casar Insulation FAQs
Has anyone documented the old buildings in the center of Casar?
Only in part. Cleveland County's 2019 survey, which covered buildings from 1945 to 1975, recorded the downtown area, with its early twentieth century cotton gin and a cinder block service station from about 1960. The report then named Casar's historic center among places rich enough to deserve a full survey. None of it is on the National Register, and by the state's account a listing would not bind a private owner spending private money. Your attic depends on how your own house was built.
Should the wiring in an old Casar house be checked before insulating?
Yes, first of all. The town was settled about 1870, so a house from its first decades may have been wired before 1930, in the era of knob-and-tube. ENERGY STAR lists that older wiring among the hazards to correct first, because insulation packed around it can start a fire. An electrician looks at it before we blow anything in. A run that is still live stays uncovered.
Could the old insulation in a Casar attic be vermiculite?
It could: about 30 percent of Casar's homes predate 1960. If a Casar attic holds a pebble-like gray-brown or silver-gold fill, leave it undisturbed: the EPA says vermiculite may contain asbestos.
Does attic insulation in Casar need a permit?
Casar Town Hall can say whether Cleveland County Building Inspections, the town itself or another office handles permits in Casar; ask before work starts.
